Description

Die Erfindung richtet sich auf ein Visier, insbesondere für Motorradhelme, umfassend wenigstens eine transparente Sichtscheibe.The invention is directed to a visor, in particular for motorcycle helmets, comprising at least one transparent viewing window.

Derartige Visiere an Motorradhelmen, Skihelmen oder Arbeitsschutzhelmen müssen einerseits die Augen des Benutzers wirksam vor Fahrtwind und Partikeln schützen, andererseits aber dem Benutzer eine möglichst uneingeschränkte und ungetrübte Sicht ermöglichen.Such visors on motorcycle helmets, ski helmets or safety helmets must on the one hand protect the eyes of the user effectively against wind and particles, but on the other hand allow the user as unrestricted and unobstructed view.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein derartiges Visier so auszugestalten, dass insbesondere Blendungen vermieden werden.Proceeding from this, the object of the invention is to design such a visor in such a way that, in particular, glare is avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Sichtscheibe mit einer Polarisationsfolie verbunden ist.This object is achieved in that the lens is connected to a polarizing film.

Aufgrund der Polarisationswirkung wird eine Blendung, z. B. durch das auf nassen Straßen reflektierte und dementsprechend polarisierte Licht, wirksam vermieden und der Benutzer hat den Eindruck natürlicher Farben mit natürlichem Kontrast.Due to the polarization effect is a glare, z. B. by the reflected on wet streets and accordingly polarized light, effectively avoided and the user has the impression of natural colors with natural contrast.

Die Polarisationswirkung muss so ausgelegt sein, dass die Transmission zur uneingeschränkten Verwendung des Visiers bei 80 bis 100% liegt, bei einer auf den Tag beschränkten Benutzung bei 50 bis 80%. Vorzugsweise ist vorgesehen, dass die Polarisationsfolie als plattenförmiges Material ausgebildet bzw. mit einem plattenartigen Trägermaterial verbunden ist.The polarization effect must be such that the transmission is for unrestricted use of the visor at 80 to 100%, for a daytime use at 50 to 80%. It is preferably provided that the polarization film is formed as a plate-shaped material or connected to a plate-like carrier material.

Die Sichtscheibe kann ebenfalls aus einem plattenartigen Material bestehen und zusammen mit der Polarisationsfolie gewölbt in einem Rahmen festgelegt sein, d. h. die Wölbung wird durch den Rahmen vorgegeben und festgelegt.The viewing window may also consist of a plate-like material and be defined together with the polarizing film curved in a frame, d. H. the curvature is given and determined by the frame.

Günstigerweise ist die Polarisationsfolie zwischen einem äußeren und einem inneren plattenartigen Material angeordnet.Conveniently, the polarizing film is disposed between an outer and an inner plate-like material.

Bei einer ersten Ausführungsform können die innere und die äußere Scheibe aus Acetat bestehen.In a first embodiment, the inner and outer discs may be acetate.

Alternativ kann auch vorgesehen sein, dass die äußere Scheibe aus Polycarbonat und die innere Scheibe aus Acetat bestehen.Alternatively, it can also be provided that the outer disc made of polycarbonate and the inner disc made of acetate.

Die Acetatscheiben bestehen insbesondere aus Zelluloseacetat, vorzugsweise Zellulosetriacetat.The acetate discs consist in particular of cellulose acetate, preferably cellulose triacetate.

Bei einer weiteren bevorzugten Ausführungsform ist vorgesehen, dass die Polarisationsfolie zwischen zwei Acetatscheiben angeordnet ist, welche ihrerseits wieder unter Zwischenschaltung eines Luftpolster mit einer Polycarbonatscheibe verbunden sind.In a further preferred embodiment, it is provided that the polarizing film is arranged between two acetate disks, which are in turn connected to a polycarbonate disk with the interposition of an air cushion.

Günstigerweise sind die Acetatscheiben an ihrer jeweiligen Außenseite mit einer Antibeschlag-Beschichtung versehen.Conveniently, the acetate discs are provided on their respective outside with an anti-fog coating.

Zwischen der Polycarbonatscheibe und den Acetatscheiben ist zur Ausbildung eines isolierenden Luftpolsters eine umlaufende Silikonraupe angeordnet.Between the polycarbonate disc and the acetate discs a circumferential silicone bead is arranged to form an insulating air cushion.

Eine weitere Ausführungsform sieht vor, dass die Sichtscheibe aus Polycarbonat besteht und an ihrer Außenseite mit einer Polarisationsfolie versehen ist, die vorzugsweise aufkaschiert ist.A further embodiment provides that the viewing window is made of polycarbonate and is provided on its outer side with a polarizing film, which is preferably laminated.

Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher erläutert. Dabei zeigen:

The invention will be explained in more detail with reference to a preferred embodiment in conjunction with the drawings. Showing:

a schematic section through a first embodiment of a visor according to the invention,
Fig. 2
a section through a second embodiment and
Fig. 3
the detail III in Fig. 2

Bei der in Fig. 1 dargestellten ersten Ausführungsform ist an einem Rahmen 1 eine Sichtscheibe 2 festgelegt, die eine äußere Polycarbonatscheibe 3 und eine innere Zelluloseacetatscheibe 4 umfasst, zwischen welchen sich ein Luftpolster 5 befindet, welches durch eine am Rande umlaufende Silikonraupe 6 gewährleistet ist.In the first embodiment shown in Fig. 1, a lens 2 is fixed to a frame 1, which comprises an outer polycarbonate disc 3 and an inner cellulose acetate disc 4, between which there is an air cushion 5, which is ensured by a circulating on the edge silicone bead 6.

Die Acetatscheibe 4 ist beidseitig mit einer Antibeschlag-Beschichtung versehen. Die Außenseite der Polycarbonatscheibe 3 ist mit einer Polarisationsfolie 7 kaschiert. Diese äußere Polycarbonatscheibe 3 ist beidseitig kratzfest beschichtet.The acetate disc 4 is provided on both sides with an anti-fog coating. The outside of the polycarbonate pane 3 is laminated with a polarizing film 7. This outer polycarbonate pane 3 is coated on both sides scratch resistant.

In Verbindung mit einer gespritzten Polycarbonatscheibe 3 ist es wichtig, die Polarisationsfolie 7 außen anzubringen, da im Falle einer Anbringung an der Innenseite die Spannungsdoppelbrechungen der gespritzten Polycarbonatscheibe 3 aufgrund der Polarisationsfolie 7 sichtbar würden und dementsprechend die Sicht beeinträchtigt würde.In connection with a sprayed polycarbonate disc 3, it is important to attach the polarizing film 7 on the outside, as in the case of an attachment to the inside of the stress birefringences of the injected polycarbonate disc 3 would be visible due to the polarizing film 7 and accordingly the view would be impaired.

Bei dem in Fig. 2 und Fig. 3 dargestellten Ausführungsbeispiel ist an einem Rahmen 1 wiederum eine Sichtscheibe 2 befestigt, die ebenfalls wieder eine äußere Polycarbonatscheibe 3 umfasst, eine umlaufende Silikonraupe 6 und im Abstand von der äußeren Polycarbonatscheibe 3 unter Einschluss eines Luftpolsters 5 eine Scheibenkombination 8.In the embodiment shown in FIG. 2 and FIG. 3, a viewing window 2 is attached to a frame 1, which again comprises an outer polycarbonate pane 3, a circumferential silicone bead 6 and at a distance from the outer polycarbonate pane 3, including an air cushion 5 Disc combination 8.

Der Aufbau der Scheibenkombination 8 ist in Fig. 3 dargestellt. Die innere Scheibe umfasst eine äußere Zelluloseacetatscheibe 9, eine innere Zelluloseacetatscheibe (ersatzweise kann auch eine Polycarbonatscheibe vorgesehen sein) 10 und eine Polarisationsfolie 7.The structure of the disc combination 8 is shown in Fig. 3. The inner disk comprises an outer cellulose acetate disk 9, an inner cellulose acetate disk (alternatively, a polycarbonate disk may also be provided) 10 and a polarizing film 7.
